摘要
桥梁顶升技术作为一项理想的加固纠偏新技术,业已广泛地应用于旧桥改造等工程实践。与传统方法比较,基于顶升技术的支座更换方法可减少中断交通时间,缩短工期,降低造价。结合某连续箱梁桥工程实例,对支座更换的施工方案、控制要求进行总结和探讨,对类似工程具有一定的参考意义.
The Synchronous Jacking up Technology of bridges, as a perfect rectification and reinforced approach, has been applied in reconstruction of old bridges. Compared to other conventional methods, the method of bearing replacement based on synchronous jacking up can decrease transportation disruption time, and cut down the period and the cost. Com- bined to an engineering example of continuous box-girder bridge, the research results, such as construction scheme and control requirement, are concluded and discussed in the paper, which is of great referential significance for other similar projects.
